Industrial S283-K32 Three-Pole Circuit Breaker

ABB S283-K32 is a three-pole molded case circuit breaker (MCCB) rated for 32 A, part of ABB's System pro M family in the S280/S283 line, designed for industrial three-phase power distribution in panels, switchboards, and motor-control gear. It is rated for up to 400 VAC and 440 VDC, with a 10 kA short-circuit breaking capacity (Icu) at 230 VAC, and it provides thermal-magnetic protection with both long-time and instantaneous trip characteristics, making it suitable for protecting feeders and motors against overloads and short circuits. Mounting is bolt-on, offering a sturdy, fixed-installation option for enclosures with clear terminal access. This ABB MCCB works with System pro M components to ensure coordinated protection across a distribution network and is commonly used to guard three-phase loads such as conveyors, pumps, fans, and other industrial equipment in commercial or industrial environments.
